Wheel disc with at least one sealing plate

Abstract

A wheel disc with at least one sealing metal sheet, which is fixed to the wheel disc in a movable manner in the circumferential direction of the wheel disc, and with at least one securing device, which is designed to secure the at least one sealing metal sheet against a displacement in the circumferential direction of the wheel disc in the correctly assembled state. The securing device has a screw, which is screwed to the sealing metal sheet and which extends through the sealing metal sheet, and a depression, which is provided on the wheel disc and which receives the free end of the screw in the correctly assembled state and the wall of which restricts a movement of the screw in the circumferential direction.

1 . A wheel disk comprising:
 at least one sealing plate which is fastened to the wheel disk so that it is displaceable in the circumferential direction of the wheel disk, and   at least one securing device that secures the at least one sealing plate in the properly mounted state against displacement in the circumferential direction of the wheel disk,   wherein the securing device has a screw, which is screwed to the sealing plate and extends through the sealing plater, and   an indentation, provided on the wheel disk, which receives the free end of the screw in the properly mounted state and the wall of which limits movement of the screw in the circumferential direction,   wherein the screw is screwed into a sleeve provided with an internal thread which is held non-rotatably in a through hole provided on the sealing plate.   
     
     
         2 . The wheel disk as claimed in  claim 1 ,
 wherein the indentation is designed as a slot extending transversely to the circumferential direction.   
     
     
         3 . The wheel disk as claimed in  claim 1 ,
 wherein the sleeve has at least one radially outward protruding projection which, during the insertion of the sleeve into the through hole, is introduced into a corresponding recess which extends from the through hole.   
     
     
         4 . The wheel disk as claimed in  claim 3 ,
 wherein the recess of the through hole is accessible from that side of the sealing plate which faces the indentation provided on the wheel disk in the properly mounted state.   
     
     
         5 . The wheel disk as claimed in  claim 1 , further comprising:
 a retainer which secures the screw on the sealing plate in the properly mounted state.   
     
     
         6 . The wheel disk as claimed in  claim 5 ,
 wherein the retainer has a securing ring which has radially outward protruding securing projections which, in the properly mounted state, engage in receiving indentations formed correspondingly on the screw and on the sealing plate such that rotation of both the screw and the securing ring is prevented.   
     
     
         7 . The wheel disk as claimed in  claim 1 , wherein the screw is rounded at its free end. 
     
     
         8 . The wheel disk as claimed in  claim 1 ,
 wherein the at least one sealing plate is held positively on the wheel disk.   
     
     
         9 . The wheel disk as claimed in  claim 7 ,
 wherein the at least one sealing plate has an edge region which is designed in the manner of a bead and is received in a correspondingly designed undercut receiving groove of the wheel disk.
